This is the second book by the author who worked in the OSS both in India/Ceylon and China. Her first book, "Undercover Girl", was published in 1946 right after the OSS was dissolved. As such, there was no security restrictions placed her book, which provides some of the best details of life in the OSS in Washington D.C. and India/Ceylon and China. Bill Donovan proofread and provided the Forward for "Undercover Girl".

After the death of her husband in 1958, who worked for Donovan both in the OSS and Donovan's law firm, the author returned to the spy world in 1959 by joining the CIA. Thus, after a long career in the intelligence community, the author published the "Sisterhood if Spies" in 1999. This book focuses on the lives of the many women who worked in the OSS and the operations they were involved in and covers all WW2 theaters. The last chapter describes how women have advanced into key positions in the CIA.
I really enjoyed both of the author's books and recommend them to anyone who has an interest in WW2 and/or the OSS.
